Abstract (en)
The invention relates to a process for obtaining carbon dioxide from furnace combustion fumes, comprising removing the water vapour occurring in the combustion fumes through successive gas compression and expansion steps; separating the carbon dioxide from oxygen and nitrogen through the use of a filter comprising a gas-separating material, such as, for example, fullerenes, zeolites or others, to obtain substantially pure gaseous carbon dioxide; subsequently optionally producing dry ice through further steps of compression and expansion of the substantially pure gaseous carbon dioxide obtained in the preceding steps.
